Recombinant corresponding to human ICOS Ligand, Asp19-Ser258, expressed in NS0 cells.
Human ICOS Ligand, also called B7-H2, B7RP-1, B7h, LICOS, and GL50, is a member of the growing B7 family of immune costimulatory proteins. Other family members include B7-1, B7-2, B7-H1 (PD-L1), PD-L2, and B7-H3. B7 proteins are members of the immunoglobulin (Ig) superfamily, the extracellular domains contain 2 Ig-like domains and all members have short cytoplasmic domains. Among the family members, they share about 20-25% amino acid identity. Human and mouse ICOS Ligand share ~49% amino acid identity. ICOS Ligand has been identified as the ligand for ICOS, a member of the CD28 family of costimulatory receptors. Human ICOS Ligand is a 309 amino acid (aa) protein with a putative 18aa signal peptide, a 239aa extracellular domain, an 18aa transmembrane region and a 33aa cytoplasmic domain. Human ICOS Ligand is expressed constitutively on resting B cells, dendritic cells, and at low levels on monocytes. The B7-H2/ICOS interaction appears to play roles in T cell dependent B cell activation and Th differentiation. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilution: Flow Cytometry: 10ul labels 10e5 cells or 50ul of packed whole blood. Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: PE conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
